Drum type electro-osmosis dehydrator for reducing power consumption by means of a narrow distance between a positive electrode and a negative electrode

Abstract

The present invention relates to an electro-osmosis dehydrator. The electro-osmosis dehydrator comprises: a sludge supply part provided on a central upper portion, the sludge supply part including a rotating part and two rollers provided under the rotating part; a drum to which DC power having one polarity is applied to a cylindrical inner surface thereof that is rotated along a shaft, the drum being provided under the sludge supply part so as to receive sludge; a caterpillar part including a power applying part orbitally operated at a position spaced a predetermined distance apart from the drum so as to apply DC power having a polarity opposite to that applied to the drum, a filter cloth provided under the power applying part, caterpillars having a plurality of holes and being provided under the filter cloth, a vinyl part disposed between the filter cloth and the caterpillars so as to prevent the sludge from leaking between the caterpillars, and a chain provided under the caterpillar; and a plurality of idle sprocket parts provided in spaces between the caterpillar part to contact the chain, thereby operating the caterpillar parts. According to the present invention, the filter cloth between a positive electrode and a negative electrode may be removed so as to narrow a distance between the positive electrode and the negative electrode, thereby reducing power consumption.

Description

technical field [0001] The invention relates to a drum-type electro-osmosis dehydrator, in particular to a drum-type electro-osmosis dehydrator which saves electricity by reducing the distance between positive and negative electrodes. Background technique [0002] Generally, an electroosmotic dehydrator is a device that can be connected to a DC power supply to form an electromagnetic field required to remove moisture combined with sludge using electrophoresis, and remove the moisture contained in sludge through its voltage difference. [0003] This electrophoretic electroosmotic dehydrator is known as "electroosmotic dehydrator (Korean application number: 10-2004-7759)"; "phase control type electric dehydrator (Korean application number: 10-2005-9928)"; "Electro-osmotic dehydration machine (Korean application number: 10-2007-46494)"; "phase-controlled electrophoretic electro-osmotic dehydration machine using three-phase AC power supply (Korean application number: 10-2008-449...

AI Technical Summary

Problems solved by technology

However, the problem with the traditional electro-osmotic dehydrator is that there is a filter bag between the positive and negative electrodes, which hinders the power supply and distances the distance between the positive and negative electrodes.

[0007] Another problem is that the filter pack is a consumable product and needs to be replaced with a new one after 6 to 9 months of use
